Comment:

 Very sorry, but I can't find the branch `bug26876_033`. Is it one of the
 ones that got lost when you recreated your github repository?

 I updated our support policy so that we will Maintain:
 * OS X / macOS supported by Tor Browser (but not Apple)
 
https://trac.torproject.org/projects/tor/wiki/org/teams/NetworkTeam/SupportedPlatforms?action=diff=13

 Let's handle support for unsupported Windows and Linux as needed.

Comment (by mcs):

 My understanding is that Apple is fuzzy about what they support and what
 they do not support, but I think it is correct to infer based on the
 stream of security patches issued by Apple that 10.11 is the oldest
 version of macOS that they still support. But as gk said, Firefox still
 supports 10.9 and 10.10, so we would like Tor Browser to work on those
 systems as well.

 Do we actually support OSX 10.9?  Apple hasn't supported it since 2016.

Comment:

 Oh, and the availability macro was only introduced in the 10.12 header, so
 there are two different bugs here:
 
https://opensource.apple.com/source/xnu/xnu-3789.1.32/osfmk/mach/mach_time.h.auto.html

 Unfortunately, I can't do the same checks for iOS, because the kernel
 headers aren't open-source. (I only have access to the latest headers,
 which claim that the symbol was introduced in iOS 8.0.) I've asked in
 #tor-mobile if they also need this fix.

 See my branch bug26876_033.

 On my macOS 10.13 with the default settings, it detects a Yosemite or
 later target, and the mach_approximate_time symbol is imported by the
 binary.

 With `-DMAC_OS_X_VERSION_MIN_REQUIRED=1009`, it detects a pre-Yosemite
 target, and the mach_approximate_time symbol is not imported by the
 binary.

Comment:

 Replying to [comment:1 mcs]:
 > I found #24427 as well as
 https://developer.apple.com/documentation/kernel/1462443-mach_approximate_time
 (which does indicate that mach_approximate_time() is available in macOS
 10.9 and newer).

 Ah, but the macOS 10.9 header doesn't actually have that symbol:
 
https://opensource.apple.com/source/xnu/xnu-2422.1.72/osfmk/mach/mach_time.h.auto.html

 In fact, the symbol is only available in the macOS 10.10 header:
 
https://opensource.apple.com/source/xnu/xnu-2782.1.97/osfmk/mach/mach_time.h.auto.html

 (The kernel version index is here: https://opensource.apple.com/ )

 So I will do something similar to #20235 here.
